Application filed January 8,.1912. Serial No. 670,043.

-1'0 a] Z whom it may concern:

and more particularly to fastening means for doors of barns, sheds andsimilar out side buildings. However the device may be applied to anydoor, gate, window or like structure.

The invention has for one of its objects, to make a bolt which cannot.-be pulled straight out of the keeper and which can not be readily openedby any one not familiar withthe combination of the device.

Another objectis to produce a simple and inex ensive device having fewparts, which are .urable and not aptto get out of order.

Other objects and novel features of the invention will be apparent fromthe following description taken in connection with the drawings, inwhich,

Figure 1 is a perspective view ot'the device applied to a door showingthe same unlocked; Fig. 2 is a horizontal plan view showing the bolt inits extreme and locked position in the keeper; Fig. is a sectional Viewalong the line 3-3 of Fig. 4, with the top member of the keeper remqvedand turned-up; Fig. 1 is a sect-ional vi w along the line 4-4: oflFig. 1looking in t e direction of the arrows showing the bolt in position;Fig. 5 is a sectional view along the line 55 of Fig. 4looking in thedirection of the arrows, the bolt being removed. 1

Referring to the drawings I provide two members, one of which maylie-secured o the door -8 and one to the door casing 9 or they may beapplied to two hinged doors.

-On'e of the said members constitutes a gui ling device for the bolt andthe other constitutes the keeper. sists of a base 10 adapted to besecured to either the-door 8' or the casing 9 by means of provided withtwo upstanding parallel cars 12, each of which has a slot 13 adapted toreceive the bolt l-L-"lhe bolt 14, consists of a single circular bar ofmetal and is bent at right angles at the end andsquared ofl'lo form aprojection or tongue 15 which engages in the keeper to lock the two.members together. The bolt 14 is also provided with The guiding devicecon- The base 10 is a knob or'lhumb piece 16 which is preferablyprovided with a screwthreaded extremity \vherhby it may be removed sothat the bolt may be taken out of the guides or ears '12. T he knob 16is secured to the bolt 14- at a sufficient distance from the projection15 to permit the latter tomove to its extreme position in the keeper.The knob 16 also constitutes a stop for the bolt 14 when slidingbackwardly and forwardly in the.

ears .12. It is to be understood that the bolt 11 is ofsufficient.length to be at all times held by the guide members 12.

The keeper consists preferably of two independent members 17 and 18inclosed within a casing which latter is provided with a keyway 20adapted to receive the tongue 15 and bolt 14. Thecasing is preferably ofa single piece of metal or a singlecasting, as isclearly shown in Fig.4, and consists of a base portion 20 and an outwardly overhangingportion 21. The'base portion 20, a

part of which constitutes one side wall of the casing, is provided withbolt holes 22, whereby the casing may be secured to a building or otherstructure by any suitable fastening means, as the screws 23. Theoverhanging portion 21 constitutes the top and other side wall of thecasing and is provided to exclude moisture from the interior of the ame.

In assembling the keeper the member 17 I is first positioned in thecasing with its smooth side abutting against the inner top wall thereofand the member 18 which constitutes the bottom wall of the casing isthen secured against the member 17 by means of the screws 19, rivets orany similar fastening means. It will be noticed that the members aredesigned to be assembled before securing the casing to the building andthe heads of the screws 19 being on the inside, will be inaccessible toany person s 100 unauthorized to take the keeper to pieces.

While the casing and member 17 are 'shown as two separate elements, itis to be understood that-the two may be, cast in a single piece but Iprefer to use the construction as shown because'it is then possible toutilize difierent combinations with the another. To acopmmodate he bodyof the pite unlike' one the combination may be varied and that bolt 14:a central passageway 24 is provided in the member 18 and leadingtherefrom are other recesses which, cooperating with the recesses inthemember 17, constitute an inde pendent tortuous or irregularpassageway surrounding the passageway 24. This irregular passageway isof suflicient width and depth to receive the projection or tongue 15therein and the latter is adapted to engage any one of the shoulders-formed by the walls of the recesses leading from'the passageway 24 andis thereby locked at various points in its projected or partly retractedposition.

The operation of the device Will be clear from the foregoingdescription. The bolt may be opened. b one who is familiar with thecombination y simply turning the bolt 14 by means of the knob or thumbpiece 16 and at the same time retracting or projecting the same, wherebythe tongue 15 will move through the tortuous passageway past theprojections forming the same said passageway.

It will be understood that the details of therefore I do not wish to belimited to the precise details as shown.

What I claim as new and desire to secure by Letters-Patent is,

1. In a device of the class described, the combination of a bolt havinga projection thereon, akeeper having a longitudinal passageway in whichthe body crow bolt may be moved, and an irregular passageway surroundingthe longitudinal passageway adapted to receive the projection of thebolt, means for concealing said projection and passage-ways from viewwhen in 0perative relation, and means cooperating with the projection tolock the bolt in the keeper.

In a device of the class described, the combination of a keepercomprising cooperating members, one of said members having alongitudinal passageway provided with recesses in the walls thereof,another member fitting against the first named member and provided withrecesses to co operate with the recesses in the first mentionedmember toform a tortuous passage waysurrounding said longitudinal passage Way, abolt provided with a tongue and adapted to be projected into the keeper,said tongue adapted to engage the walls'of the recesses to lock the boltin the keeper.

3. In a device of the class described, a 'door casing and a door, a boltprovided with a tongue adapted to slide laterally on the door, a keeperon the casing to receive the bolt, said keeper having a longitudinalpassageway and a tortuous passageway, the passageways communicating onewith the other, means for concealing said passage ways from View, thebody of the bolt adapted to reciprocate in the longitudinal passagewayand the'tongue on said bolt movable in said tortuous passageway andmeans cooperating with the tongue to lock the bolt in. the keeper. v

In testimony whereof I allix my signature in presence of two witnesses.
